Longitudinal Outcomes of Gender Identity in Children (LOGIC)
LOGIC is a longitudinal study on the development of gender identity in children and young people in the United Kingdom and the Republic of Ireland. The study follows children and young people who were referred to the UK Gender Identity Development Service when they were aged 3–14 years, and their parents or caregivers, regardless of whether families choose to remain in contact with the service. The study consists of a main survey and a qualitative sub-study, LOGIC-Q.
